WTE@ STATES PATENT @FFIQE JOHN F. OCONNOR, or CHICAGO, ILLINOIS, AssIGNon To WILLIAM H. MINER, OF CRAZY, NEW YORK.

YOKE.

Application led August 21, 1916.

To all 'LU/wm t may concern Be it known that I, JOHN F. OCONNOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Yokes, of which the following' is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in yokes.

An object of the invention is to provide a detachable connection, of simple construction, between a draw bar and yoke for railway draft riggings.

In the drawing forming apart of this specification, Figure 'l is a side elevation of a draw bar and yoke illustrating one form of i the invention. Fig. 2 is a horizontal sectional view taken substantially on the line 2 2 of Fig. 1. Fig. 8 is a vertical, sectional view and end elevation taken on the line 3 3 of Fig. 1. And Fig. 4 is a detail perspective of the locking element employed in the improvement.

In said drawing, 10 denotes the shank of a draw bar or coupler, the latter having a butt 11. The side faces of the butt 11 are grooved or channeled as indicated at 12-12 for the purpose hereinafter described. The yoke A comprises upper arm 13, lower arm 14, rear connecting portion 15 and a hooded forward end. The hood of the yoke A, comprises an upper horizontal wall 16, the lower horizontal wall 17, and side walls or plates 1818. The inner faces of the side walls 18-18 are channeled or grooved as indicated at 19-19, opposite the channels or grooves 12 of the draw bar butt when the latter is assembled with the yoke as indicated in Fig. 2. The upper and lower walls 16 and 17 of the yoke hood are perforated in alinement with the grooves or channels 19, as indicated at 20-20 to thereby receive the arms 21-21 of a U-shaped locking pin illustrated in Fig. 4. rlhe upper ends of the arms 21 are preferably wedge shaped or tapered, as indicated at -22 and said arms are connected at their bottom by cross portion 23. The arms 21 are substantially rectangular in cross section and extend partly within both the grooves or channels 12 and 19, as clearly indicated in Fig. 2. The bottom wall of the hood is provided with a pair of spaced, perforated de- Spcci'cation of Letters Patent.

pending ears 24 located at the front and rear of the bottom portion of the locking member when the latter is in position, said ears being adapted to receive a cotter 25 to retain the locking member in operative position. if

The parts are assembled by first inserting the butt of the draw bar within the yoke hood and placing the grooves 12 of the butt into alinement with the grooves 19 of the hood. Thereupon, the U-shaped locking member is inserted vertically through the bottom wall of the hood and the arms thereof engage within the grooves 12 and 19, thus preventing relative longitudinal movement between the draw bar and yoke, as will be apparent from an inspection of Fig. 2. The locking member is then held in position by inserting the cotter 25.

I claim:

1. In a device of the character described, the combination with a yoke having a hooded forward end, of a draw bar, the butt of which is insertible within said hood, opposite walls of the draw bar butt and the corresponding adjacent walls of the hood having opposed grooves when the draw bar and yoke are assembled, and removable means insertible between said walls of the butt and said walls of the hood and engaging in said grooves to thereby prevent relative longitudinal movement between the hood and yoke.

2. In a device of the character described, the combination with a yoke having a hooded forward end, the side walls of which are provided on their interior with vertically extending grooves, of a draw bar, the butt of which is insertible within said hood, the sides of the butt being grooved to correspond with said grooves of the hood, and a U-shaped locking member inserted vertically through the hood and having the arms thereof engageable within the grooves of the draw bar butt and hood.

3. In a draw bar and yoke connection, the combination with a yoke having a hooded forward end, the inner faces of the side walls of the hood being provided with vertically extending grooves, and the top and the bottom walls of the hood being perforated in alinement with said grooves, of a draw bar, the butt of which is insertible within said hood, the side walls of the butt being grooved in transverse alinement with said grooves of the hood, and a. U-shaped locking member insertible vertically through the perforations in the bottom Wall of the hood, the arms of said member engaging partly in both the grooves of the hood and the grooves of the dravv bar butt.

4. In a draw bar and yoke connection, the combination With a yoke having a hooded forward end, the inner faces of the side Walls of the hood being provided With vertically extending grooves, and the top and the bottom 'walls of the hood being perforated in alinement with said grooves, of a. draw bar, the butt of which is insertible Within said hood, the side Walls of the butt being grooved in transverse alinement With said grooves of the hood, and a U-shaped locking member insertible vertically through the perforations in the bottom Wall of the hood, the arms of said member engaging partly in both the grooves of the hood Aand the grooves of the dravv bar butt, and means for retaining said locking member in position.

In Witness that I claim the foregoing I have hereunto subscribed my name this 19th day of JAug. 1916.

JOHN F. OCONNUR.
